In this context, it is essential that the nurse knows in depth this nursing diagnosis. The objective of this study is to build a medium-range theory for the nursing diagnosis Sedentary Lifestyle in adolescents and young adults. This is a methodological study, according to specific theoretical frameworks for the development of medium-range theory. The study was made operational through an integrative literature review in the databases: National Library of Medicine and National Institutes of Health; Scopus; Cumulative Index to Nursing and Allied Health Literature and Web of Science. The crossing of the following descriptors Sedentary Behavior; Sedentary Lifestyle; Young Adult; and Adolescent allowed 2974 articles to be obtained. After applying the eligibility criteria, the final sample resulted in 57 articles. The results show the identification of 3 essential attributes; 10 clinical antecedents and 8 clinical consequents. The essential attributes were cultural and personal aspects, physical inactivity and physical activity lower than recommended. The clinical antecedents were advanced age; deficient knowledge; unemployment; insufficient personal and environmental stimulation for physical activity; feminine gender; physical inactivity; physical activity lower than recommended; live in an urban area; excessive screen time on internet and / or television; and, prolonged sitting time. And the clinical consequents were cardiovascular alteration; excess adiposity; lack of physical conditioning; impaired cognitive function; backache; impaired memory; impaired mental health; and, inadequate sleep time. Then the medium range theory of that diagnosis was developed and presented by means of a pictogram. The development of a mid-range theory for the nursing diagnosis Sedentary lifestyle, provided an in-depth study of the causes and consequences of this health problem that affects a large part of the general population. It is concluded that the understanding of nursing diagnosis sedentary lifestyle based on a mediumrange theory is timely and generates tools that can promote health and quality of life in this specific population.Acesso AbertoComportamento sedentárioTeoria de EnfermagemAdulto jovemAdolescentemasterThesis
